The Lowdown
Alright folks, Rusty here. Let’s talk about what’s on offer for the Kennebunk Beach stretch.
Look, I’ll be straight with you – the next week and a half is a tough watch. We’ve got a long dry spell on our hands. From Sunday the 6th right through to Thursday the 17th, it’s basically a surf desert. There’s nothing worth paddling out for. The swell is tiny, the periods are short, and the energy is weak. The water temp is about average for this time of year, so no surprises there, but that doesn’t help the lack of waves.
The only glimmer of hope, and I mean the *only* one, shows up on Friday the 18th. It’s a long way off, so don’t get too attached yet, but the models are hinting at a late-season pulse of energy. Friday morning sees a jump in size with a 7ft ESE swell, but with a short period of 6 seconds, it’ll be a bit dumpy. The wind is light and offshore from the NE, so the surface will be clean.
Then, Friday afternoon is where it gets interesting. The swell is 8ft from the ESE, period bumps up to 8 seconds, and the combined energy jumps to 704 – that’s a solid push of power. With light offshore winds, it’s shaping up to be the standout of the whole outlook. This is big enough that it’s really only for the experts; beginners should sit this one out. The break is sheltered, so it will need that direction to hit it right.
Saturday the 19th morning holds onto that energy with a 6ft ESE swell and a 9-second period, combined energy of 559. The wind is offshore again, so it’s clean. The afternoon will see the wind shift and the quality drop off a bit. After that, it’s back to fading into nothing by Monday the 21st.
So, the one true standout is Friday afternoon, September 18th, at Kennebunk Beach. It’s the only real window of quality surf in the whole 16-day run. Keep your fingers crossed the forecast holds.
Rusty, signing off.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
